It looks like Amazon has slipped up and listed the Ryzen 3000 refresh CPUs (now taken down), namely the Ryzen 5 3600XT and the Ryzen 9 3900XT for €284 and €569, respectively. Both listings mention the embargo and launch date of the processors, and they are in line with earlier rumors. The announcement should come on the 16th of June, followed by a launch on the 7th of July (7/7).

CPU | Ryzen 5 3600X | Ryzen 5 3600XT | Ryzen 7 3800X | Ryzen 7 3800XT | Ryzen 9 3900X | Ryzen 9 3900XT |
---|---|---|---|---|---|---|
Base Clock | 3.8 GHz | 4.0 GHz | 3.9 GHz | 4.2 GHz | 3.8 GHz | 4.1 GHz |
Boost Clock | 4.4 GHz | 4.7* GHz | 4.5 GHz | 4.7 GHz | 4.6 GHz | 4.8* GHz |
L3 Cache | 32 MB | 32 MB | 32 MB | 32 MB | 64 MB | 64 MB |
TDP | 95W | 95W | 105W | 105W | 105W | 105W |
Launch | July 2019 | July 2020 | July 2019 | July 2020 | July 2019 | July 2020 |

Interestingly, the boost clocks mentioned here are lower than what other sources had earlier claimed. We’re looking a boost clock of 4.5GHz for the 3600XT (just 100MHz higher than the 3600X) and a boost of 4.7GHz for the 3900XT (again, just 100MHz higher than the 3900X). Furthermore, the prices are also a notch above the existing Ryzen 3000 parts.
Where the 3600X costs 189 pounds in the UK, this listing puts its 100MHz higher refresh at 249 pounds, a hefty 50 pounds more. Similarly, the 3900XT appears to be priced 120 Euros more than the stock 3900X. Keep in mind that the boost clocks aren’t the only changes to the Matisse refresh. We are also expected to get a faster Infinity Fabric clock (2000MHz vs 1800MHz on the vanilla chips) which should directly improve latency, thereby improving the gaming performance. Coincidentally, the gaming performance is the only metric where AMD’s Zen 2 chips lag behind the newly announced 10th Gen Comet Lake-S lineup. We should have more info on this soon.
